Twitter and Google have been playing together more as of recent. Few months ago, Google started including recent and relevant tweets alongside search results on your mobile phone.
Today, the company announced that those same results are being included on desktop search as well.
As on mobile, the integration of Twitter with Google's desktop search engine will give you different results depending on what you're looking for. If you search for an individual, you'll get a scroll of their most recent tweets. But searching for a more general topic (like the "NASA Twitter" example Google uses in its blog) will show both tweets from the official NASA account as well as tweets from others users talking about NASA. Some of our staff have seen this feature rolling out already, but as of today it should be open to all.
